MicroPython v1.15 on 2021-04-18; ESP32 module with ESP32

When trying to advertising with a long payload(longer than 31 bytes) using bluetooth lib on esp32, Micropython would give an unclear error code " OSError: -18 ".

import bluetooth
esp32_ble = bluetooth.BLE()
esp32_ble.active(True)

payload = b'\x02\x01\x06\n\taLongName\x11\x07\x9e\xca\xdc$\x0e\xe5\xa9\xe0\x93\xf3\xa3\xb5\x01\x00@n'

esp32_ble.gap_advertise(interval_us=200000, adv_data=payload)
# Traceback (most recent call last):
#  File "<stdin>", line 6, in <module>
# OSError: -18

A payload longer than 31 bytes might be generated with a 128bit Service UUID and a long name(len>8).

from ble_advertising import advertising_payload    #example in /micropython/example/bluetooth

ServiceUUID = bluetooth.UUID("6E400001-B5A3-F393-E0A9-E50E24DCCA9E")
payload = advertising_payload(name="muchTooLong", services=[ServiceUUID])

A short name would work just fine.
The error code is not helpful for debugging, but I'm not sure how to improve this.
I opened this issue to notify who have met the same problem.
